In the boom several nozzles are mounted to deliver the liquid mix from the attached tank. The pump is basically a motor with the speed to be controlled for the n转向 发表于 2025-3-22 10:32:09
Peter Wapnewskig, applications of control theory and methods have been still limited in variable-rate spray application control, agricultural vehicle control, greenhouse control, and aeroponic system control. In agricultural cybernetics the control objects are more complex, and the scales may vary from a field, aSIT 发表于 2025-3-22 16:51:21

Marketing margins widen greatly, reducing the incentive to modernize as roads become worse or non-existent.

Agriculture stands out relative to other sectors in the centrality of modern science to its progress. Research results must reach farmers and farmers’ requirements must feed back to research. As
